Background/Purpose:
We aimed to assess the effects of Helicobacter pylori (H. pylori) eradication on the rebound of reflux-related symptoms among gastroesophageal reflux disease (GERD) patients.
Methods:
This prospective randomized study recruited patients with typical reflux symptoms and reflux esophagitis on esophagogastroduodenoscopy (NCT02934152). Patients positive for H. pylori via a urea breath test (UBT) were randomly assigned to receive bacterial eradication with triple therapy for 2 weeks either before or after proton-pump inhibitor (PPI) treatment for 4 weeks. Follow-up was implemented with serial GerdQ evaluation and a subsequent UBT. The primary outcome was the incidence rates of symptom rebound between patients with and without H. pylori infection. The secondary outcomes included the severity of symptom rebound, incidence rates of symptom rebound, and successful eradication rates between the early and late eradication groups.
Results:
A total of 248 patients were enrolled, of whom 107 (43.1%) tested positive for H. pylori infection. All patients with and without concurrent H. pylori infection had significant symptom improvement over the entire treatment. Patients with H. pylori infection had significantly lower rates of symptom rebound (19.8% vs. 34.2%, p = 0.034) and rebound severity (1.8 ± 0.7 vs. 2.8 ± 1.6, p = 0.031) 4 weeks after eradication and PPI treatment than those without. The incidence rates of symptom rebound and successful eradication rates were not significantly different between the early and late eradication groups.
Conclusions:
GERD patients with concurrent H. pylori infection were less susceptible to symptom rebound after H. pylori eradication compared to those without.
